But he really wasn't featured much in last year’s "The Force Awakens," minus that final, already legendary scene.
He opened up to the thousands of fans about what he thought, especially after working his butt off to lose so much weight before the film.
As for Luke's absence from most of the film, he said, "I wasn’t insulted. I thought it was a really great surprise," according to Entertainment Weekly.
"But I don’t think they prepared me correctly," he continued. "I went to training and I lost all this weight. I thought, ‘I must be doing something physical if they’re sending me to the gym twice a week and torturing me physically.”
He added, "‘Oh, by the way, all that workout where you lost all the weight? You’re going to have to turn, and remove your hood.’”
Hamill, 64, also explained his reaction to reading the script.
"What are the very first words in the crawl? ‘Luke Skywalker has vanished.’ I said, ‘Hoo, this is gonna be good,’” Hamill said.
But that's it, until the end, really. He did think he was going to appear at a very crucial scene.
“In the forest, when the lightsaber [wiggles] like this and flies off," he said, "I thought, ‘Oh, what a great entrance!’ GAH! Rey caught it? She hasn’t even been to [fictional planet] Dagobah for training! What’s the deal?"
